hwmon: (w83627ehf) Fix number of fans for NCT6776F
commit 585c0fd8216e0c9f98e2434092af7ec0f999522d upstream.
NCT6776F can select fan input pins for fans 3 to 5 with a secondary set of
chip register bits. Check that second set of bits in addition to the first set
to detect if fans 3..5 are monitored.
